A standard protection in the doors with no drive is the manual bolt (used in the doors without a lock) that makes it impossible to lift the shut doors from the outside.

The clasp lock used optionally in the KRISPOL doors is operated from both sides and installed from the interior. The lock is recommended for the doors installed in the garages with no additional entrance.

The obstruction sensor is a standard equipment of the doors with the electric drive. It prevents possible accidents associated with crushing. In case of any obstacle while closing (e.g. a ladder of a scooter), the door will automatically stop and then it will be raised, without causing any damage.

Another element installed in the door with the electric drive and preventing unpleasant experiences is the pressure blockade that makes it impossible to raise the lowered door from the outside and thus protecting it against burglary.

The application of photocells protects against crushing. The door is lifted automatically when any obstacle is found at the level of the photocell line.

The sections structure is another protection for they form the door armour, due to which the possibility of crushing one’s fingers from the outside and from the inside is eliminated.
